To all whom it may concern: 7

Be it known that I, WILLIAM J. KILPAT- RICK, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Adding and Listing Machines, of which the following is a' specificatio This invention relates to that class of adding and listing machines which, while operating normally to register and print amounts to the full decimal capacity of the keyboard, is adapted for sub-division of printing and accumulating mechanism so as to provide for simultaneously running two or more separate columns or lists of items.

The principal object of the present invention is .to arrange in a machine of this particular kindfor utilizing one section or subdivision of the accumulating mechanism for keeping count of the number of itemizing operations of the balance of the accumulating mechanism and printing the count simultaneously and along the same horizontal line with the imprint of the total of amount accumulation. In this connection that section ofthe printing mechanism corresponding with the counting section or subdivision of the accumulating mechanism will be disabled during counting operations, though restored to operati'veness for the printing of the count total. When the ma-- chine isthns in use for keeping count of the number of itemizing operations means come into play for preventing-an overrunning of the amount register section or subdivision of the accumulating mechanism from afl ecting the section orsubdivision of the accumulating mechanism used for counting purposes, the usual transfer devices being disabled at the point of subdivision.

While adapting the machine for such use as above described the invention makes provision for an alternate use whereby two separate columns of imprints can be made, one of amounts beingaccumulated and the otherof dates or designating numbers not accumulated, the section or subdivision of the accumulating mechanism which corre sponds with the section or subdivision of the prlnting mechanism used for date or deS-' ignating number printing being then utilized to take care of any over-flow from the other section or subdivision. of the accumulating mechanism in which amounts are be,-

ing registered. In this connection the machine is adapted to print any total thus extended beyond the point of subdivision, the cipher or ciphers beingautomaticallyfilled in notwithstanding no digit occurs int-he total at the first decimal place to the right of the point of sub-division and that during the itemizing there has been a suspension of cooperative action between-the impression devices at this point.

The accompanying. di' part of this specificationtillustrate the invention as embodied" in an adding and listing machine of the well-known Burroughs type (see William S. Burroughs Patents Nos. 504,963 and 505,078, dated September 12, 1893), but it is to be understood that the invention is not necessarily limited to em- 'bodiment in this particular type of machine.

Reference may also be had to English Patent No. 656 of 1908- and United States Patent No. 908,430, issued December 29, 1908, on the inventions of J. G. Vincent.

Of said drawings, Figure 1 represents the machine in sectionalized left side elevation with the parts relatively positioned as when the machine is operating under normal conditions; Fig. 2 is a somewhat similar view. showing a less number of parts, the latter appearing relatively positioned as when the machine is arranged or adjusted for count-- ing the itemizing operations; Fig. 3 is a somewhat. similar view illustrating the effect of depressing the total key when'such' conditions obtain; Fig. -41- is another sectionalized left side elevation showing the parts relatively positioned, as when the machine is arranged to print two columns and extend the total; Figs. 5 and 6 are vertical sections taken on lines farther to the right than the preceding figures and illustrating the countcontrolling devices, Fig. 5 showing the same at normal and Fig. 6 illustrating such parts in action; Fig. 7 is a horizontal section taken on the line 7-7 of Fig. 6; Fig. 8 is a partial front elevation of the machine with some parts in section; Fig. '9 is a section taken substantially on the line 99 of Fig. 8; Fig. 10 is'a fragmentary sectionalized top plan view taken substantially on the line 10-10 of Fig. 1; Figs. 11, 12 and 13 are vertical sectional views of coupling devices in the printing mechanism, Fig. 11 showing the parts at normal, Fig. 12 showing the same'under a date or designating number the means for firing the hammers.

adjustment, and Fig. 13 showing these parts under an extended total adjustment; Fig. 14 is a horizontal section taken on the line 1414: of Fig. 1; Figs. 15, 16 and 17 show examples of work which can be performed by the machine when equipped with the present invention.

In the drawings, the reference numeral 291 designates the usual depressible amount keys arranged in parallel rows and the keys of each row inscribed from 1 to 9. These keys operate upon small bell cranks 217, to which are coupled stop rods or wires 270 whose laterally turned forward ends slide in slots of fixed upright plates 210 at the front of the machine. The bell cranks as usual operate slip strip or bars 214; which coact with well-known detent devices not necessary to describe or illustrate, and these strips or bars displace the usual latches J5 which normally uphold segmental racks 610 and the front ends of levers 611 with which said racks have the usual slot and pin and spring connection. The levers 611 are loosely mounted on a rock shaft 600 carrying the usual restoring frame or bail 613 and at their rear ends said levers carry segmental series of type plates 618 adapted to be driven against a roller platen 17 by impression' hammers 715. The latter coact in the usual way with pivoted hammer drivers 716, normally restrained by pivoted latches 717, the latter adapted to be individually displaced by pivoted pawls 718 held in engagement. with the latches by springs 780 connecting said pawls with the hammer drivers 716, said springs also constituting The pawls 718 are as usual carried by a rocking bail and formed with tails to coact with cam shoulder on the levers 611 so the latches will not be individually tripped unless the corresponding levers move far enough to present digital type at the printing line.

The numeral 910 designates the left-hand side piece of a rocking frame such as ordinarily employed to support the registering wheels and pinions, and those which in the present instance operated in the ordinary way are designated b the numerals 920, and 916. The numeral 9 0 designates the pivot shaft of said rocking frame, which shaft extends from side to side of the same, and 958 and 958 designate studs such as are usually located on the left-hand side piece of this rocking frame above and below said pivot shaft. These studs are adapted as usual to coact with a pitman 91 1 which is coupled to a three armed lever 913 carrying studs 961 and 961 which are operated upon by a wipe pawl or plate 821; the latter. carried by a rock arm 813. The usual link 911 is coupled to the pitman and through slot and pin connections attached to a bell crank lever 227 which is surmounted by the usual total key 265. Said bell crank lever is also connected with a bail 22 1 adapted to simultaneously withdraw all of the latches 115 when the total key is depressed.

All of the above described parts are familiar in Burroughs adding machines and they operate in the well-known manner.

In carrying out the present invention the stop wire connections for the 1 key of one bank (in this instance the third bank or row from the left) are modified over those usually employed to provide for the counting operation which calls for repeating the single step movement of a wheel or pinion or of the primary one of a set of wheels or pinions. In the present instance the modification in stop wire connections being in the third bank from the left, three wheels are employed to register the count and the primary wheel is of course that one farthest to the right, the same being designated 920 in Fig. 8 and its pinion 916. The bell crank 217 (Figs. 5 and 6) on which the 1 key above referred to operates does not connect directly with the associated stop wire 270 but has a one way engagement with an arm 2 on the same cross-shaft 200 on which said bell crank is loosely mounted, which enagement may be effected by means of a stud e on the bell crank acting against the front edge of said arm. The stop wire 270 is con neeted to said arm, from which it will be obvious that depression of this 1-key will result in retracting sa id stop wire in the usual way, but it is obvious the stop wire may be retracted by rearward movement of the arm independently of the key bell crank and it is adapted to be so retracted for the purposes of the counting operation. The arm .2 has at its lower extremity a finger 2 (Fig. 7) projecting laterally to the left he hind a plate Z which is mounted to rock loosely upon the aforesaid shaft 200 and act with its rear edge against said finger e to effect the retraction of the stop wire. Said plate is normally held. forward and upward by a spiral spring 2 in an inoperative position as shown in Fig. 5. A spring-held bail 424 similar to that commonly employed in Burroughs machines is constructed and arranged as usual to be swung rearward by any one of the detent strips 21 1, each of the latter having a downturned lip 214E bearing against cross rod 402 of this bail. In the present instance the bail has an additional intermediate arm 121 which, at a point just above the cross rod 4102 is formed with a flange 2 projecting to the right, Fig. 7, and adapted to act against the forward edge of the plate Z, though under normal conditions it passes freely under said plate (see Fig.

Under the lower keyboard plate 212 there is slidingly mounted a plate Z which near its forward end is formed with a downwardly projecting cam portion 2 adapted of the plate Z, and thereby lower said plate adjustment and it for a drop of the associated however, said plate X when the plate is slid forward would ordinarily trip the printing hammer to do with the operations of a third slide to act'upon a roller 2" carried at the upper forward corner; far enough to bring its front edge directly behind the flange a of the bail arm 424. The cam portion 2 of-said plate Z" is sufficiently flattened at its apex to preserve the will be seen that depress1on of any amount key by swinging the bail 424 rearwardly will cause the plate Z to be swung rearwardl-y, carryingwithit the arm a by reason of the engagement between the rear edge of the plate and, the finger 2 of said arm. This retracts the stop wire 270 as shown in- Fig. 6 and provides rack 610 the correct distance for registering 1 on the associated number wheel when the rack is returned to normal. It will thus be seen that by sliding the plate Z forward the machine will be adjusted for registering thecount of itemizing operations,'it being understood that the count accumulations are carried from the Wheel 920 to the next adjacent wheel 920 to the left and from the latter to the remaining wheel 920 through the usual transfer mechanism.

As it is not desirable to print a row of when the machine is operating under the counting adjustment, special provision is made for disabling the pawl 718 which belonging to the third bank from the left! This particular pawl is provided with a stud m, Fig. 2, projecting laterally from 'its tail portionfor coaction with the angular lower edge of onearm of the bell crank lever X pivoted on a cross rod 200 and carrying at the extremity of its other arm a roller w. A plate X is mounted to slide on the under side of the lower keyboard plate 212 and cooperate with said roller, this plate having two downwardly projecting cam portions 00 r with flattened apexes and: a depression between them. A spiral spring tends to draw the bell crank X forward to effective position but normally the plate X stands rearward with its forward cam projection 00 over the roller :20, see Fig. 1,, which has the eflect of holding the lower end of the bell crank so far rearward and upward as to have no effect upon the pawl 718. When, is moved part way forward, accompanying the forward movement of the plate Z before referred to, the depression of said plate X permits the bell cranklever Xto assume the effective posi tion illustrated in Fig. 2, so that inan operation of the machine the pawl 718 will be disabled through coaction between its stud w and the angular lower'edge of said lever, as illustrated by dotted lines in Fig 2. The operating connection. between the two. plates X and Z will be later pointed out,- having the total key bell crank 'from the plate with functions besides that of simply amounts, it becomes necessary to displace the bell crank lever X and to this end there is secured 'tothe rock shaft 204 on which 227 is secured, a. rearwardly curved arm X? whose rear edge is adapted to act against a roller stud wi on said bell crank lever X with the eflect illustrated in Fig. 3, where the bell crank lever X is shown carried away trip its latch.

Most of the latches 717 have the usual overlapping tails cl, Fig. 14, to provide for the trlppin of one latch by another to accomplish t e familiar result of filling in ciphers. This automatic action, however, should be. suspended, when the counting operation is in progress, between the sections or subdivisions of latches, one of which is associated with. the sub-division or section of the printing mechanism which is listing the lower end of said' pawl 718, leaving the latter free to amounts belng accumulated and the'other of which is associated with that portion of the printing mechanism used simply to record the total of the count. Hence the third latch to the right designated 717 does not have one of the overlapping tails a? but itis operatively connected with the next adjacent latch to the right by a movable coupling piece A of a similar character to that disclosed in the Gooch Patent No. 825,205, dated July 3,1906. This coupling-piece has at its forward end oppositely projecting ofiset studs a normallyengaging notches in the upper edges of the two latches, so that through the medium of this coupling piece thelatch 717 may trip the adjacent latch to the right, the same as though the usual overlapping tail was present. However, the coupling piece, besides being mounted to slide on a cross rod 706 to accommodate the rocking of the latches, is pivotally movable about said cross rod to uncouple the latches. It will thus be seenthat in the printing of totals ciphers between the count total and the amount total may be eliminated, as in the example of work shown by Fig. 16.

A forward extension of the coupler A is connected by a spiral spring a with an overhead bracketa said spring thus tending to engage the coupler with the latches.

many p g so acts in order to preserve the cooperative relationship between latches. A bail B is pivotally mounted between the side frame pieces above the coupler and the forward cross bar of the bail isact upon the forward extension of the coupler in opposition to said spring a, said bail having a forward projection b which is connected to an underlying fixed stud bbya spiral spring 6 superior in strength to'said,

adapted to of the coupler A spring a. Said bail is, however, normally held up against the stress of said spring 6 through means hereinafter described.

In the present instance the arrangement is such as to provide for efiecting the split or subdivision of the printing mechanism for extended total purposes at a different point from that at which the split is effected for count purposes. In the present instance the printing of dates in the left hand column under an extended total adjustment being contemplated, only two banks of keys need be employed for the left hand column work and the printing mechanism split between the second and third decimal places counting from the left. The second latch 717 is notched in its upper edge similarly to the third latch 717 previously described and a coupler A is employed between these two latches, said coupler being a duplicate of the coupler A as to its rear portion, which has studs 0, for engaging the latches. This second coupler A engages the cross rod or shaft 706 in the same manner as does the coupler A, so as to slide thereon when the cou ler A is in engagement with the latches $17 and 717 and also adapted to rock on said shaft to disengage from said latches. A spiral spring a connects the forward extension of the coupler A to the overhead bracket a said spring normally enforcing engagement of the coupler with the latches. A bail B overlies the said forward extension and underlies the beforementioned bail B and the forward extension of the coupler A, anda spring 6 connecting said bail B with the stud 7) tends to lower the bail and when free to do so overpowers the spring a rocking the coupler A to disengage it from the latches '7 17 and 717". A vertically disposed bar 0 is slid ingly mounted in the frame-work and formed at its lower end with a shouldered portion 0 engaging under a stud I) which projects from the left side of the bail B. Said bar is upheld by a spiral spring C, Fig. 1, of suflicient strength to overcome both the spring b and the spring 5 The upper bail B has a lip 19 Fig. 1A, projecting from the left side and overlying a portion of the bail B. The bar C normally upholds the bail B with its front cross bar spaced from the forward extension of the coupler A as shown in Fig. 11, and also upholds the bail B by reason of the engagement between the lip 12 of the latter and the underlyin bail B. Hence the springs a and a are free to normally enforce engagement between both couplers A and A and their latches.

A strip or bar C is'suitably mounted to slide on the under side of the lower keyboard'plate 212, Fig. 4, and at its rear end has an irregular formation providing stepped shoulders c 0 with cam surfaces leading to them. The bar C carries at its upper end a roller 0 for coacting with this irregular portion of the slide strip or bar C Normally, as shown by dotted lines in Fig. 1, said roller bears against a plain portion of the strip to the rear of the irregularly formed portion, the said strip being then in its foremost position. When the strip is slid rearward one step its cam surface just in rear of the step 0 acts upon the roller 0 and thrusts the bar C downward, the roller coming to rest upon said shoulder. This downward movement of the bail is sufficient to permit lowering of the upper bail B to the position shown in Fig. 12, said bail displacing the coupler A. The lower bail B moves downward also but not far enough to act upon the other coupler A. Movement of the slide strip C another step to the rear causes its cam surface just in rear of the shoulder a to act upon the roller 0 and thrust the bar C farther downward, said roller coming to rest on said shoulder, as shown in Fig. 4:. This further downward movement of the bar C permits further lowering of the bail B as illustrated in Fig. 13, said bail then acting to displace the coupler A. When this takes place the other coupler A should be restored to normal position and to this end there is loosely mounted upon the cross rod or shaft 706 a cam plate D which is adapted to act upon a down-turned cam flange. I) of the upper bail B. Said cam plate is formed on the upper side of said cross rod or shaft, with a nose to act upon said cam flange and on the forward side of said cross rod or shaft with a finger b to be acted upon by the lower bail B. It results that when said bail B is lowered far enough to displace the coupler A it rocks the cam plate, causing the latter to lift the bail B, the spring 6 being superior to the spring b The slide strip C is operatively connected to the beforementioned slide strips Z X by levers a and w pivoted intermediate their ends upon the upper side of the lower keyboard plate 212 and having slot and pin connections at opposite ends with the slide strips, the pins extending through slots in said keyboard plate. The slide strip C has at its forward end a post a projecting through slots in the keyboard plates, and surmounted by a knob or finger piece C above an index plate C secured on the keyboard as shown in Fig. 10 and slotted to accommodate the post 0 The said knob has an index finger 0 adapted to register with any one of three inscriptions on the plate, suchinscriptions in the present instance being an abbreviation of the word normal, to-wit NorL, the word Count and the word Date. Movement of the knob to bring its pointer c opposite the word Count carries the strip C one step rearward with the effect on the coupling devices already described. This movement of said strip is accompanied by forward movement of 'the stripsZ' and X with other results already described, to-wit the rocking of the cam plate'Z so that the stop rod or wire 270 will come into action for count purposes, and the rocking of the lever 'X to efi'ective position for disabling a section of the'printing mechanism;

It has beengbefore stated that the racks 610 have the usual slot-and-pin connection with the levers 611. These racks are as usual spring-drawn in upward direction for the purpose of carrying as in the ordinary Burroughs machine and they are normally restrained from movement under the impulse of the springs by the usual transfer pawls 413. The racks cooperate severally with pinions 916, 916 916 and '916", and'thelatter have the usual transfer projections for tripping the pawls 413. In the present in- 'ions move stance, however, the pinions do not all remain at all times axially aligned as in previous machines. They do so remain as long as the knob C is not moved to the Date position but when the knob is moved to the latter position the two pinions 916 and 916 and the number wheels 920 and 920 carried by them, which belongto the two left-hand rows of keys, may remain out ofengagement with the racks 610 while the remaining pininto engagement with their racks. Thus the racks to the left of the split may return to normal without affecting their pinions and the only movement imparted to the pinions will be that which takes place by reason of the over-running of the pinions to the right of the split. vious that .a total to the right of the split can be extended to the left of the split.

Now the two left-hand pinions and their number wheels are carried in an inner frame movable about the shaft 900 independently of the main frame of which the side plate 910 is a part. This main frame as usual comprises intermediate plates 910 besides a right-hand plate similar to the left-hand plate 910, and also a tie rod 910". wheels and pinions to the right of the split are separately mounted as usual between pairs of plates 910 Plates 920 somewhat similar to the usual plates 910 are used to the left of the split but are slotted at e where they embrace the tie-rod 910*. These special plates 920 of which there are fourmake up the inner frame before mentioned, together with shorttie-rods 920 which connect the plates. The frame thus composed supports in its upper-portion the two lefthand pinions and number wheels independently mounted for rotation in much the same way as the balance of the pinions and wheels It will be noted that this inner frame may rock on the shaft 900 independently of the latch F is Thus it will be ob- The main frame an extent determined by the length of the slots c. This is suficient to provide for disengagement of the two lefthand pinions'from their racks while the remaining pinions are engaged with their racks. The left-hand side plate 920 of the inner frame has a forwardly and; downwardly extending arm 920 which carries a screw stud f at its extremity. On this stud-are loosely mounted a pair of latches F and F, each separately drawn downward by springs f and f", tending to engage the latches over stud 958,.which is elongated for the purpose. When either of these latches is engaged with that stud the inner frame is locked to the main frame and will operate as though a part of it. The lefthand. latch F is normally disengaged from said stud by reason of the fact that the upper edge of the pitman 914 just in rear of its notch abuts the under-edge of the latch as shown in Figs. 1' and 4, but the right-hand the rear of the and remains so as long as the knob C -is not moved to the Date adjustment. The strip C which is slid back and forth by the said knob has at an intermediate point a camrise 1f.v When the strip is moved beyond the Count adjustment, that is to say when the knob is moved to the Date position, this cam-rise of the strip acts upon a roller f carried in the rear end ofan arm F secured to the rock-shaft 200 and extending in rear thereof. The depression of this arm by the rearward movementof the strip rocks the shaft and elevates an arm F secured to the latter and projecting forwardly. This arm F is connected by a dependent link F with the latch F, said link being hooked under a stud on said latch as shown at f in Figs. 1 and 4. A spring F draws downwardly upon the arm F permitting the latch F to maintain its engagement withthe stud 958 so long as the knob C is not moved to the Date position.

With the knob at the Date adjustment and the inner frame unlatched from the regular accumulator frame, in an itemizing operation both frames will be swung for: ward in the usualway, the tie-rod 910 carrying the inner frame along with the outer frame. However, the inner frame will not.

be returned with the outer frame, not being latched thereto and hence the two left-hand racks in rising will have no effect upon the pinions in this inner frame. It will thus be seen that so long as the inner frame is unlatched there can be no accumulation of amounts on the wheels in that frame as a result of the depression of keys in the two left-hand banks. However, it is of course necessary in order to secure the extended total that these two left-hand wheels shall return to mesh with their racks in time to take transfers from the wheels to the right normally engaged with the studand from one to the other. Therefore, means are provided for rocking the inner frame just as the handle reaches the end of its return stroke and immediately after the restoring bail 613 has reached its home position. The left hand plate 920 of the inner frame is extended downward as clearly shown in Fig. 1 and there is jointed to it a link 920 which at its rear end is curved and slotted as shown at g to engage a stud g on the rocking arm 813. This last-mentioned figure of the drawings illustrates the relation of parts under a Date adjustment just as the handle is about to finish its return stroke and the stud g is about to strike the righthand end of the slot 9'. its action against that end of the slot is sufficient to thrust the link 9520 far enough to rock the inner frame and engage its pinions with the racks. Then it will be obvious that if the adjacent wheel of the regular set has tripped its transfer pawl the carrying movement will take efiect upon the right-hand one of the two wheels in the inner frame'and if that movement imparted to such wheel carries it past the nine position then it will in turn tripthe trans fer pawl associated with it and cause a carrym g movement to take place in the other wheel in the inner frame.

As the extended total wheels may be out of mesh at the time the transfer pawl is tripped by the adjacent wheel of the regular set, 1t is necessary to provide means for preventing the transfer or carrying movement of the rack for the right-hand one of the extended total wheels, until that wheel comes into mesh with the rack. Such means are illustrated in Figs. 1, 4i; and 9 and it will be observed that there is' swung from the same stud that supports the transfer pawl 413 another pawl 413 having a finger h separated from its main portion a-little more than the diameter of the usual stud 4:14 on the rack which cooperates with the regular transfer pawl. This finger it normally stands in rear of that stud as shown in Fig. 1 so that it does not obstruct the same. This auxiliary transfer pawl is drawn forward by a spring 2' but is normally held rearward by the inner accumulator frame, one of whose plates 920 is formed with a rearwar'dly and upwardly projecting arm 72, having a forwardlyturned upper end portion with a laterally projecting flange 7L standing in front of the lower rounded extremity h of the auxiliary transfer pawl as clearly illustrated in Fig. 9. When the inner frame rocks forward the auxiliary transfer pawl follows it by reason of the action of the spring 11 and the finger h is then brought to position over the stud 414 as illustrated in Fig. 4. The rocking back of the regular frame of course has no eflect upon this auxiliary pawl. It continues to restrain the rack until the inner frame rocks back and its pinions are engaged with its eeaaeo racks. Then the restrained rack is released by the auxiliary pawl and the transfer may take lace; To prevent the inner frame from acci entally returning to mesh with the racks its weight is supplemented by a spring 7' tending to hold the frame in its outer position, said spring beingattached to a forwardly projecting arm of one of the plates 920 and to a fixture on the lower part of the regular side plate 910.

in order to print the extended total it will be understood that all the hammer driver latches should be cooperatively related. Of course durin the itemizing under the Date adjustment the split is efiective. This means of course that the coupler A is raised out of engagement with the second and third latches counting from the left. When an extended total is to be taken this coupler should be restored as of course the accumulator wheels to the left of the split come into play. To this end means are provided whereby the depression of the total key will result in restoring said coupler to operative position. To this end the bail B is formed with an angular rearward extension B which extends under a roll on on the rear end of a curved lever Mwhose upwardly extending arm has pivotally connected with it a link M (Figs. 1 and 14) longitudinally slotted to embrace a stud m upon a rearward projection of the vertical bar C. The link has an upstanding rear portion carrying a stud MP. A spring on attached to the link M tends to draw the same forward and therefore elevate the rearwardly-extending arm of the lever M and prevent it from af fecting the bail B. The bell crank lever 227 on which the total key is mounted is connected by a link 226 (Fig. 1) with an arm 227* depending from and secured to a rockshaft 206, and the latter has secured to it another depending arm N bent over and doubled back at its lower extremity (see Fig. 14) forming a foot n adapted to operate upon this stud m under certain conditions. It will be noted that the position of the link M is determined by the adjustment of the bar C and the latter is of course determined by the manipulation of the knob C While the knob remains either at Normal or at Count adjustment the bar C is not lowered far enough to bring the said stud m in line with the foot 11 (see Figs. 1 and 2). Consequently inthe taking of a total no effect is produced upon the bail B by depression of the'total key. However, when the knob O is moved to the Date position the shoulder c of the irregular portion of the'strip C rides over the roll 0 on the bar C and further depresses the latter. This brings the stud m in line with the foot 91,. Consequently when the total key is depressed said foot acts on the stud and draws the link M rearwardly, rocking the lever M and raising the bail B notched latches 717 and 717".

by pressure of the roll at u on the forward extension of said, bail. T is ermlts the coupler A to become engage with the tripping from right to left throughout the entire series of latches takes place.

Of course it will be understood that m order to obtain the extended total all the, pinions must remain in. engagement with their racks during the forward stroke of the Now the spring j as well operating handle. as the weight of the inner accumulator frame and-its two pinions 'andwheels will tend to disengage these pinions from their racks as the arm 813 startsrearward re-, 7 lieving the link 920' of the restraint imposed upon it by the stud g. It is in this connection that the latch F comes into play. It will be recalled that thislatch is normally upheld by the pitman 9.14 so as not to engage the stud 958 (Figs. 1 and 4). When the pitman is lowered by depression of the total key said latch F drops behind the said stud 958 and thus prevents thedisen'gagement of the two pinions from their racks. All of the accumulating pinions move out of mesh with their racks at the beginning of the rear or return stroke of the operating handle as usual in the taking of a grand total on a regular Burroughs machine. Of course at the conclusion of the operation the pitman 914 rises to its normal position and lifts the latch F butthe inner accumulator frame has meantime been rocked through the medium of the link 9520 so as to engage the two extended total pinions with their racks at the same time that the balance of the pinions are returned to engagement with the racks through the usual means, comprising a rearwardly projecting arm 919 secured to the rock shaft 900 near its right-hand end and having a cam edge acted upon by a roller 311 on the full stroke sector 311, all as illustrated in Fig. 1.

The usual form of locking means is employed to prevent turning of the pinions when disengaged from their racks, said locking means comprising a frame journaled on the shaft 900 and composed of side plates 926, intermediate plates 926 with looking noses, and cross rods 926". Said frame cooperates with the usual locking lever such as,

against the front ends of the slots e. Consequently the extended total pinions are locked against turning just the same as though they were mounted in the ordinary,

Hence the lzecyond the roller a,

tends to draw said finger .has an angular arm 01:

- arm w carrying It will be understood that when the knob C is moved to the Date position the re-' sultant forward movement of the slide strip Z will carry 1ts cam portion a forwardly so asto disable the cunt devices, and likewise the forward movement of the slide strip X will cause its second cam portion m Fig. 2, to act on the roller w to disable the lever X.

In order to guard against a possible miscount' of operations when the machine is adjusted for utilization of the three left-hand wheels for counting purposes, by reason of transfer actuation of the right-hand one of those three wheels, means are provided for disabling the transfer mechanism betweensuch right-hand wheel and the left-hand Wheel of'the regular set, whenever the machine is adjusted for counting purposes. Thus, the rack belonging to the pinion of said right-hand countlng wheel is prevented from partaking of extra movement, notwithstanding the regular pawl restraining that rack may be displaced by the transfer projection of the left-handpinion of the regular set and said pawl latched in its displaced position in the regular way. Referring to Fig. 9, the reference numeral 413 designates an auxiliary pawl mounted upon the same pivot stud that supports the regular pawl 413, said auxiliary pawl having a finger 'w adapted .to engage over the stud 414 of the rack belonging to-the right-hand counting wheel. Under a normal adjustment of the machine this finger stands in rear of said stud, as illustrated by the posi tion of pawl 413 in Fig. 1, though a spiral spring w attached to the auxiliary pawl over the stud to the position shown in Fig. 9.- The pawl pivot and presenting a rear edge 103 to a roller 40 on the depending arm w of a bell crank lever having a forwardly projecting a roller w adapted to cooperate withya cam portion a of the slide strip G A spring w draws the bell crank arm 10 forward and, being superior to the spring w or acting on the auxiliary pawl through greater leverage, normally holds the lower arm of the pawl rearward, so that the I finger w will not obstruct the stud 414, but

the latter may pass into a notch w of the auxiliary pawl. Normally the roller e0 lies against a plain portion of the strip C but When said strip is moved rearward to the Count position, as shown in Fig. 9, the cam w acts upon said roller, rocking the bell crank and permitting-spring w to draw the finger w over the stud 414. The apex of the cam portion 10 is flattened for the purpose of preserving the adjustment, but

when the strip is moved farther rearward to the Date position said cam portion is carried in rear of the roller to so that the finger to will be again moved to the rear of the stud aid and the transfer mechanism be ermitted to act as usual.
